Ball bearing construction reduces friction during door operation and supports consistent, smooth swing over the service life of the hinge. This hardware is suited for interior and exterior door installations in residential and light commercial applications. Licensed contractors and finish carpenters install this type of hinge during new construction and renovation work where a square-corner profile and a matte black finish are specified. The hinge weighs approximately 2.1 pounds per pair and ships as a single pair unit.\u003c\/p\u003e\n\u003cp\u003eThis hinge is designed for standard door applications where a full-mortise, square-corner hinge with ball bearings is required. It fits doors where the leaf size calls for a 4.5 inch x 4.5 inch footprint. Typical installations include interior passage doors, entry doors, and utility doors in both residential and light commercial settings. The black finish coordinates with contemporary and transitional hardware styles and is appropriate for use with black door levers, knobs, and other architectural hardware in the same finish family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5 inch x 4.5 inch square hinge leaf dimensions for full-mortise installation\u003c\/li\u003e\n  \u003cli\u003eBall bearing construction for smooth, low-friction door operation\u003c\/li\u003e\n  \u003cli\u003eBlack finish suited for contemporary and transitional door hardware sets\u003c\/li\u003e\n  \u003cli\u003eSold as a pair, consistent with standard door hinge replacement and new installation practice\u003c\/li\u003e\n  \u003cli\u003ePackaged dimension: 6.4 inches x 3.2 inches x 1.8 inches per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation hinge for standard full-mortise door applications requiring a 4.5 inch x 4.5 inch square-corner hinge profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a finish carpenter, general contractor, or licensed door hardware installer.
